I am so <CF_CONFUSED> !!! I have created a shopping cart to add for the
purchase of computer systems, and everything works ok if their is just
one computer in the cart. I can update the quantity etc just fine. My
problem comes in when I add another computer to the cart and then try to
do an update of the quantity or delete it. When I hit update it looks
like the items in the Array are switching places. IE : The sysModelNum
is where the unitCost is suppose to be and so forth. I cannot figure it
out. Do I need to loop over the items again on the update somehow to
stop this from happening, and if so could someone give an example. I am
posting portions of the code I am using to see if someone can see my
error in logic. PLEASE HELLLLPPPPPP!!!!!!!!
This is the cart page after the form is submitted, it posts back to
itself for update or delete
<CFLOOP COLLECTION="#session.cart#" ITEM="i">

This is the struct that I created to hold the values of the computer
system and handle the updates
THIS IS CALLED AS A CUSTOM TAG IN THE ABOVE PAGE
<CFSCRIPT>
if (not(isDefined("session.cart"))){
session.cart = structNew();
}
tempValue = listToArray( '#attributes.sysModelNum#,
#attributes.price#,
#attributes.qty#,
#attributes.cse#,
#attributes.cpu#,
#attributes.ram#,
#attributes.hdd#,
#attributes.sec_hdd#,
#attributes.mtr#,
#attributes.ctr#,
#attributes.vid#,
#attributes.snd#,
#attributes.cdr#,
#attributes.dvd#,
#attributes.crw#,
#attributes.modem#,
#attributes.stg#,
#attributes.spk#,
#attributes.nic#,
#attributes.clng#,
#attributes.os#,
#attributes.war#' );
// Check to make sure that the item is in the cart, and if it is not
add it.
if (not(structKeyExists(session.cart,attributes.sysModelNum))) {
structInsert(session.cart,attributes.sysModelNum,tempValue);
}
else {
// If the item is already in the cart update the quantity
tempvalue[3]=session.cart[attributes.sysModelNum][3]+attributes.qty;
structUpdate(session.cart,attributes.sysModelNum,tempValue);
}
</CFSCRIPT>
and this is the delete part
THIS IS CALLED AS A CUSTOM TAG IN THE ABOVE PAGE
<CFSCRIPT>
if (isDefined("session.cart")){
if (StructKeyExists(session.cart, attributes.sysModelNum)) {
structDelete(session.cart,attributes.sysModelNum);
}
}
</CFSCRIPT>
I hope someone can help
